Quantum teleportation

Quantum teleportation, step by step. Although the details of their experiments differ, both the NIST and Innsbruck teams have achieved deterministic teleportation of a quantum state between trapped ions:
First, an entangled state of ions A and B is generated, then the state to be teleported -- a coherent superposition of internal states -- is created in a third ion, P.
The third step is a joint measurement of P and A, with the result sent to the location of ion B, where it is used to transform the state of ion B (step 4).
The state created for P has then been teleported to B (image and text credit: H J Kimble and S J van Enk Nature)
